1. The laser wavelengths are different: the laser wavelength of the fiber laser marking machine is 1064nm, the laser wavelength of the ultraviolet/UV  laser marking machine is 

355nm, and the laser wavelength of the carbon dioxide/CO2 laser marking machine is 10640nm.

2. Different lasers: fiber laser marking machines use fiber lasers, carbon dioxide/co2 laser marking machines use CO2 gas lasers, and ultraviolet/UV laser marking machines 

use short-wavelength ultraviolet lasers, which are cold light engravings.

3. Different application fields: CO2 laser marking machine is suitable for engraving most non-metal materials and some metal products, fiber laser marking machine 

is suitable for engraving most metal materials and some non-metal materials, and UV laser marking machine can It can clearly mark all plastics and other materials that

 have adverse reactions to heat. It is especially suitable for applications such as marking food and medical packaging materials, drilling micro holes, high-speed dividing

 of glass materials, and complex pattern cutting of silicon wafers.
